Application filed April at,

To all whom it may concern:

Be it known that I, CLAUDE F. JONES, a citizen of the United States,residing at Dill city, in the county of VVashita, State of Oklahoma,have invented certain new and useful Improvements .in Fire-Extinguishers; and i do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to new and useful improvements infirecxtinguishers, and particularly to devices of this character forextinguishing fires in cotton gins.

One object of the present invention to provide a novel and improveddevice whereby the gin man can quickly and easily start the feed waterpump of the steam boilers in the engine room, without the necessity ofnotifying the engineer and asking his assistance.

Another object is to provide a novel and improved device of thischaracter whereby hot water can be directed on the burning cotton toextinguish the fire, thisbeing more effective than cold water.

A further object is to provide a novel and improved controlling valvewhich simultaneously permits steam from the bo1ler to enter the steamcylinder of the pump and water to be pumped through the usual feed waterheater to the gin room where the fire is located instead of to theboiler.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation 01 my improved fire extinguisher for cottongins.

Fig. 2 is a top plan view of the same.

Fig. 3 is an enlarged vertical sectional view through the controllingvalve.

Fig. 1 is an enlarged vertical sectional view through the check valve.

Referring particularly to the accompanying drawing, 10 represents thewater cyl1nder and 11 the steam cylinder of a pump. The pump is locatedadjacent the boiler 12, a steam conveying pipe 13 being connected to theboiler and to the said steam cylinder for delivering steam to saidcylinder to actuate the pump. A yoke-shaped branch pipe 1 1 is connectedat its ends with the steam Specification of Letters Patent.

metrically opposite ports 19 and 20. Rota= table within the casing is atapering valve plug 21 which is formed with two transverse ports 22 and23 which are arranged to register respectively with the ports 17 and 18and the ports 19 and 20. The intermediate portion of the yoke 14 isconnected to the valve casing at the ports 18 and 20 so that steam fromone arm of the yoke will be permitted to how through the port 23 andinto the other arm of the yoke, and thence to the steam cylinder oi thepump. Connected with the boiler and with the water cylinder of the pumpis a pipe 24 which conveys hot water to the boiler from the pump, thelatter drawing it from a feed water heater as indicated.

In this pipe 24: there is interposed a valve casing 25, and in saidcasing is mounted a check valve 26 for preventing back pressure from theboiler. Connected to the pipe 24, and to the casing 16, at the port 19,is a pipe 27. Connected to the casing 16, at the port 17, is a branchpipe 28 which leads to the gin room, where it is connected to a hose(not shown), for use by the operator in directing water on the burningcotton.

The larger end of the valve casing 16 has screwed thereon a cap 30 forretaining the valve therewithin. The other, or smaller end of the valveis formed with a reduced stem extension 31 which projects through thesmaller end of the casing, and is formed with a rectangular portion 32for the reception of the radial crank arm 33. The smaller end of thecasing 16 is externally threaded to receive thereon the threaded cap 341and through which the said extension or stem 31 projects. Encircling thestem 31 between the cap and the crank arm 33, is a coil spring whichserves to draw the valve into firm frictional contact with the interiorface or bore of the casing whereby a watertight and steamtight joint isprovided.

In the steam pipe 13, between the arms of the yoke or branch 14:, thereis disposed the controlling valve 15, by means of which steam can bepermitted to pass directly from the boiler to the engine cylinder whenthe engineer desires to replenish the water in the boiler.

From the foregoing it will be apparent that when a tire occurs in thegin room the operator there has only to pull the operating rod 36, whichis connected to the outer end of the crank arm 83, to .open the valve21, and permit steam from the boiler to pass to the engine cylinder.This Will result in the immediate starting up of the pump, with theconsequent pumping of hot water from the I heater through the valve 21and pipe 28 to the gin room, where the operator can water will flow intothe boiler as usual. Un-

der ordinary circumstances the engineer starts the pump by opening valve15, closing it again when the water in the boiler has been replenished.But when a fire occurs and a distant operator opens the double valve bypulling on the rod or wire 36 andstarting the pump as above described,the water will flow through the branch pipe 28 rather than toward thebeiler because when the latter occurs it wouid meet with resistance.

a check valve in this pipe opening toward the boiler; of a branch pipeleading from the water pipe between the pump and check valve to the ginroom, an engineers valve in said steam supply pipe, a branch steam pipeleading around this valve, a single valve for controlling bothbranchpipes, and means for operating this valve from said gm room. 7

In testimony whereof, I aifix my signature, in the presence of twowitnesses.
